COIN CONTROL MECHANISM FOR VENDING MACHINES s Sheets-Shaft 3' Filed Sept. '7, 1955 INVENTOR. 7 PAUL E. MARCUSON H/S ATTORNEYS United States Patent Q COIN CONTROL MECHANISM FOR VENDING MACHINES Paul E. Marcuson, Campbell, Calif. Application September 7, 1955, Serial No. 532,364 7 Claims. Cl. 194-75 This invention relates to coin controlled dispensing machines and more particularly to a coin actuated mechanism therefor. More specifically the invention herein entails the provision of a coin actuated mechanism adapted to be coupled for operation by the presence of a single coin of large denomination or a plurality of coins of lesser denomination.

Briefly stated the invention contemplates a vending machine in which the presence of either a fifty cent piece or two twenty-five cent pieces is required in the coin contr'ol mechanism in order to couple the same for operation.

In connection with the foregoing object is a further object to provide a novel coin carriage and toggle operated mechanism associated therewith for positively actuating article discharge means when proper coin or coins are present in the coin control. This entails a coin carriage having a coin receiving pocket provided with a zone for a single coin and another zone for several coins either of which must be filled to the right value before coupling operation can occur.

These and other objects and advantages of the present invention will become apparent in the following description in the light of the drawings in which: a

Fig. 5 is a view similar to Fig. 4 with parts thereof in a difierent position.

"ice

there be noted that the carriage gate 11 includes a push plate 17 connected to the fore wall of the frame 15 and guided for sliding movement therewith. This push plate becomes a temporary ledge for the next lowest article while the lowermost one is being discharged That is to say, While the carriage gate 11 is shifted to its rearmost or article discharging position the push plate 17 supports the next lowermost article until the carriage gate 11 returns to normal (foremost) position, whereupon the next lowermost article drops into the frame 15 and onto the ledge 14 for support thereby.

The coin controlled carriage gate 11 is operated with and by the coin control mechanism 20 now to be explained. The coin control mechanism 20 is situatedbetween the article feed passage and the front wall F.0f the cabinet C for ready receipt of a coin orcoins deposited in a coin slot 21. i

The coin slot 21 is formed through the front wall F of the cabinet C and communicates with a coin passage or runway 22 associated with or passing through testing or detector means 23 by which spurious coins or slugs are separated from valid coins by which the coin control is intended to be operated. For purposes of the present invention the detector means 23 may be of any well known design to serve the purpose.

The coin control mechanism 20 embodied in the present invention comprises a housing H consisting of side plates 2627 separated from each other by suitable spacers 28 to receive a coin between them. In the present disclosure the coin control mechanism is constructed to receive and handle either a fifty cent piece or two twenty-five cent pieces. Consequently, the spacing" of plates 2627 from each other is such as to receive a silver half dollar between them. These plates 2627 and their separators 28 as shown comprise a housing H secured in the cabinet C preferably to the front wall F. The rearmost edge of the housing H ends adjacent the fore wall 29 of the supporting structure 30 for article passage P.

Between the rearmost portions of the side plates 2627 is an over-center or toggle lever 31 pivotally mounted, midway its ends, on a pin 32 having its ends journaled in bores provided in the side plates 2627. The upper end 33 of lever 31 extends above the upper edges of plates 2627, is bifurcated, and has its rearmost tine inserted through a slot formed through the fore end of the push plate 17 hereinbefore mentioned. Thus it will be seen Referring to the drawings -10 indicates a vending machine with cabinet C which encloses a stack of vendable articles A in the form of cylindrical containers arranged for gravitation through a feed passage P toward a coin controlled gate carriage 11 at the lower end of such passage. As seen in Fig. 1 several lateral passagesL have additional articles stored therein on inclined runways 13 for admittance into the main feed passage P when the stack of articles therein diminishes to the level of each successive lateral runway. 1

The lower end of passage P terminates in a ledge 14 extending at least halfway across the bottom of the passage so that the lowermost article A rests on the ledge 14. The coin controlled carriage gate 11 comprises a bottomless frame 15'through which the lowermost article can pass except for the ledge 14. This carriage gate 11 is arranged for sliding movement to and fro beneath the passage P so as to shift the lowermost article from supported position on the ledge 14 to the upper end of a discharge passage 16 as best illustrated in Fig. 2 It will that the push plate 17 and frame 15 of the gate carriage 11 reciprocate to and fro responsive to rocking motion of toggle lever 31 between its two extreme positions. Adjacent the birfurcated upper end 31 of lever 31 is a pin 34 having one end of a tension spring 35 secured thereto. The opposite end of spring 35 is connected to an upturned tab 36 on plate 26 of the stationary housing H. This tab 36 is in vertical alignment with the pin 32 about which lever 31 rocks so that the lever 31 snaps into either of its two extreme positions by reason of the toggle action of the spring 35 and pin 34 at the upper end of lever 31.

Also arranged between side plates 2627 is a coin carriage 37. This coin carriage 37 comprises a foot portion 38 of substantially half the length of the housing H and normally disposed in the fore half thereof. A pair of lugs 3939' extend laterally from foot portion 38 into guideways 40 and 40' formed in side plates 2627, respectively. These guideways 40-40 serve to guide the lugs 3939' and to support the coin carriage 37 for sliding movement to and fro within the housing H.

The aft end of the coin carriage 37 comprises a vertical arm 41 formed integrally with the foot portion 38. The aft edge 42 of arm 41 is formed by two angular faces having their apex 43 disposed in a plane horizontally opposite the fulcrum point for toggle lever 31 as provided by pin 32. The upper end 44- of arm 41 is pro vided with a partially annular socket and a similar socket 45 is formed on the fore face of the lever 31 inra horizontal plane opposite the upper end of arm 41. These sockets 44 and 45 receive ball-like ends of a link 46 for connecting the coin carriage 37 to the upper end of the toggle lever 31.

Substantially midway between its fore and aft ends the foot portion 38 of coin carriage 37 has a partially annular socket 47 formed in its upper edge to receive the ball-like lower end 47' of a manually operable lever 43. This lever 48 has a lateral pin 49 extending therefrom and through a horizontal slot 49 formed in side plate 26. A tension spring 53. having one of its ends connected to pin 49 and its opposite end anchored to a lug 51 extending from the outer face of the plate 26 serves to maintain lever 48 in its normal or foremost position. To this end part 28' of the spacers 28 provide a stop for the lever 48 for maintaining the latter in a substantially vertical position.

It should here be noted that the fore edge of lever 48 has a shoulder 52 formed just ahead of the neck of the ball-like lower end thereof. This shoulder 52 bears against the upper edge of the foot portion 33 to prevent the lever 48 from rocking beyond its normal angle of repose as when it is in normal position abutting the stop 28'. Thus it will be noted that the tension spring 51 not only serves to yieldably urge lever 48 toward its normal position but also to draw the coin carriage 37 toward its foremost position relative to the guideways 40-40 in the housing 25. Note also, however, that the toggle spring 35 acting upon toggle lever 31 also tends to urge the coin carriage toward its foremost position when the upper end of lever 31 passes over center of the pin 32 about which the toggle lever rocks. It will therefore be apparent that when the upper end 33 of toggle lever 31 is in'its foremost position so is the coin carriage 37 in its foremost position.

The lever 48 has its fore edge disposed for abutment by the aft end 53 of a plunger 54. This plunger 54 is guided for sliding movement in a bushing 55 mounted in the front wall F of the cabinet C and has its fore end protruding from the cabinet C to provide a push button adapted for manual operation. The push button or plunger 54 is spring loaded for normally extending the fore end 55 thereof beyond the front wall F of the cabinet. In this manner the plunger 54 is retracted to normal position independent of the operation of the lever 48.

Upon application of pressure against the push button end 55 of plunger 54 its inner end 53 engages the lever 48 to urge the latter in an aft direction. However, in the-absence of a coin or coins between the upright arm 41 of coin carriage 37 and the lever 48 the latter will merely rock about itsball-like lower end 47 see Fig. 5. Consequently, no movement occurs in the coin carriage since it remains in its foremost position by action of the toggle spring and lever 31.

In order to effect actuation of the coin carriage 37 in accordance with the present invention it is necessary that the plunger actuated lever 48 be coupled to the vertical arm 41 of the coin carriage. This is accomplished by the disposition of a proper coin or coins between these two elements by reason of the shape of the opposing faces of the latter as will now be explained.

The coupling aspects of the lever 43 and vertical arm 41 is afforded by the pocket 56 formed between them. This pocket 56 as illustrated in Figs. 4 and consists of two levels I and 11. Level II which is lowermost in the coin carriage 37 is for handling two coins each of onehalf the value of a single coin intended for disposition in level I. Level I is uppermost in the pocket 56 because the single coin of larger denomination is of greater diameter than the two coins intended to be received in the lower level II of the pocket.

As best seen in Fig. 4, when the lever 48 is in its foremost position and vertical arm 41 and foot portion 33 are in normal or retracted position, the pocket 56 formed thereby is relatively V-shaped. With the parts thus disposed, the open upper end of the V-shaped pocket 56 is in register with the discharge end of the coin detector means 23. Consequently, all coins which are cleared for discharge from the lower end of the detector means will fall by gravity into the pocket 56.

As previously stated, the present disclosure illustrates the device as intended for operation by either one fifty cent piece (one-half dollar) or two twenty-five cent pieces .25 and .25 (two quarter dollars). The fifty cent piece .50, being of larger diameter than either of the two quarter dollars pieces, will become wedged in the upper end of the V-shaped pocket 56. In this connection both the aft face 57 of the lever 48 and fore face 58 of vertical arm 41 is configurated to provide a restrictive passage 59 in the upper end of the pocket 56.

The restrictive passage 59 includes a ledge 60 formed on a projection-60 from the fore face 58 of arm 4 Between this ledge 60 and the socketed upper end 44' of arm 41 the fore face 58 is recessed as at 61 on an arc of lesser radius than the radius of a coin .50 of fifty cent denomination. The restrictive passage 59 also includes a dome-like formation 62 formed on the after face 57 of lever 43. This dome 62 is configurated to register with and conform to the recess 61 so as to fit into the same as shown in Fig. 5. That is to say, when no coin is present in the pocket 56 the lever 48 will rock into the position as shown in Fig. 5, upon full inward stroke of the plunger 54, and no rearward movement of the coin carriage 37 will occur.

When a valid fifty cent coin .50 is discharged into the upper end of the pocket 56 such coin will become lodged above the restrictive passage 59 as at X in Fig. 4. In other words, the periphery of the coin .50 rests upon the tip of ledge 60 and against the dome 62. it should here be noted that an imaginary line I struck across the passage 59, i. e., the points of contact of the coin .50 with the edge 60and dome 62 is of lesser distance than the diameter of coin .50. Thus it will be understood why the coin .50 becomes lodged above the restrictive passage. More important, however, it will be noted that the tip of the ledge '60 is lower than the point at which the coil] .50 tangently engages the dome 62. Consequently upon manual depression of the plunger 54 and resulting rearward rocking of the lever 48 (to dot-dash position Fig. 4) the newly deposited )COlIl .50 will ride up the ledge 60 until the periphery of coin .50 engages the rounded upper end 44' of arm 41.

.The coin .50 now engages the fore face 58 of arm 41 at two points while being engaged at one point, substantially midway between such two points, by the dome .62. At this juncture it should be remembered that the lower end 47 of lever 48 is connected to the foot portionfitl of the-coin carriage 37 and therefore the lever 48, coin .50 and coin carriage 37 become as a solid block upon continued rearward pressure against the plunger54.

From the foregoingit will be appreciated that the coin .50 acts as a coupling agent for effecting rearward movement of the coin carriage 37 during the balance of the full stroke of the plunger 54 against the lever 48. As previously stated, in the absence of the coin .50 the lever 48- would merely rock up to but not aginst the vertical arm 41 and no operation of the-coin carriage would occur. a

When a valid twenty-five cent piece .25 is discharged from the detector means 23 into the V-shaped pocket 56 such coin will pass through the restrictive passage 59. It should here be noted that whilethe restrictivepassage 59 (line I) is of lesserdimension than the diameterof a fifty cent coin it is of greater dimension than the diameter of a twenty-five centcoin. Consequently valid twenty-five cent pieces will fall into-the lower zone of the V-shaped pocket 56 as illustrated by the coin Y in Fig. 4.

The base of the V-shaped pocket 56 includes a concave seat 56 on the upper edge of the foot portion 38 and an upwardly tending curved surface 63. This curved surface 63 merges with the fore edge 58 of the vertical arm 41 and terminates in a recess 64 just below the projection 60 upon which the ledge 60 is formed. The recess 64 is scribed on a radius comparable to that of a twenty-five cent piece so that if only one quarter .25 is disposed in the lower zone of the V-shaped pocket 56 such single quarter will be forced up the curved surface 63 into recess 64 upon rearward swinging movement of the lever 48. When the lever 48 returns to normal or retracted position by action of its return spring 51 the single quarter .25 will roll back down the inclined or curved surface 63 and remain in the base of the pocket 56.

From the foregoing it will be seen that if only one quarter .25 is in the pocket 56 no operation of the coin carriage 37 can occur. However, when the second twenty-five cent piece .25 enters the lower zone of the pocket 56 it will stand upon the first quarter .25, see Fig. 4. Note here that the space between the periphery of coin .25 and the bottom edge of the projection 60' is of slightly lesser dimension than the diameter of a twenty-five cent piece, i. e., one of the coins intended for deposit in the lower zone of the pocket 56. Consequently the two quarters .25 and .25 in the lower zone of pocket 56 stand one upon the other between the opposing faces 57 and 58 of the lever 48 and vertical arm 41, respectively. Moreover, these two coins .25 and .25 bridge the gap between the base 56 of the pocket 56 and the underside of the projection 68. In this connection note in Fig. 4 that in the lower region of the pocket 56 the aft edge 57 of the lever 48 has a slight curvature so as to tangentially engage both coins .25 and .25 when they bridge the gap between the base of the pocket and underside of the projection 60'. At this stage the lever 48 is in the same radial position of its swing as when the dome 62 would engage the periphery of a fifty cent piece as previously explained.

From the foregoing it will be appreciated that the two quarters .25 and .25 serve to couple the plunger actuated lever 48 to the vertical arm 41 of the coin carriage 37 for the balance of the full stroke of the plunger 54 against the lever 48. Thus it will be seen that when either two quarters or one fifty cent piece is disposed in the V-shaped pocket 56 the coin carriage is coupled to the lever 48 for movement therewith upon continued movement of the plunger toward fully depressed condition.

When the coin carriage 37 is coupled to the plunger actuated lever 48 by the presence of a proper coin or coins .1

therebetween, the coin carriage 37 will slide between plates 26-27 to the position shown in Fig. '2, when the plunger 54 is pressed all the way in. Since the toggle lever 31 is connected by link 46 to the coin carriage 37 movement of the latter toward full stroke position will rock the toggle lever 31 clockwise against the action of its spring 35. Thus the toggle lever is rocked over center and into the position shown in Fig. 2 with the assistance of the spring 35. It will thus be seen that even though the push button 55 has not been fully depressed, the coin carriage 37 will be shifted toward full stroke position by action of the toggle lever spring 35.

The actual discharge of an article from the ledge 14, however, requires the full stroke of the plunger 54 by manual depression of the button end 55 of the latter. As previously stated the upper end of lever 31 is con nected to the push plate 17 which extends forwardly from the bottomless frame of carriage gate 11. Consequently the article confined within the frame 15 is shifted by rearward movement of the latter. In this manner the bottommost article is shifted off of the ledge 14 for discharge by gravity into the upper end of the discharge passage 16. Note at this juncture that the parts of the device are positioned as illustrated in Fig. 2. Note also that the side plate 27 of housing H carries a coin displacing leafspring 65 in the lower zone 11 of the -V- shaped pocket 56 and 65 in the upper zone I thereof. These springs 6565 are secured to the outer face of the side plate and extend through slots formed therein so that the springs 65-65 press the coin or'coins toward the opposite side wall 26 when the coin carriage is in full stroke position. The side wall 26, Figs. 1. and 3 has a coin discharge aperture 66 formed therein adjacent the position assumed by the coins in the coin carriage 37 when the latter is in full stroke position.

From the foregoing it will be appreciated that as soon as plunger 54 is released for return to its normal position neither a fifty cent piece nor the two quarters will be gripped between the lever 48 and the vertical arm 41 of the coin carriage. Consequently the coin discharging leaf Spring 65 will press a fifty cent piece .50 through the discharge aperture 66 or in the event two quarters .25'and .25 were used, the lowermost quarter .25 will be pressed out first and the uppermost quarter .25 will fall right behind the first for discharge through the aperture 66. Coins discharging through the aperture 66 will fall into a cash box 67 in the usual manner.

In connection with the discharge of each article from the ledge 14 the falling article actuates a resetting mechanism for the coin control mechanism 20. This resetting mechanism includes a resetting lever 68 pivotally mounted as at 69 on a stationary portion of the supporting structure 30 for the article passage P. Resetting lever 68 has a paddle 70 extending rearwardly from its lower end into the discharge passage 16 for engagement by a falling article just discharged from the ledge 14. This opposite or upper end of the resetting lever 68 is linked by a pin and slot connection 71 to the lower .end 72 of the toggle lever 31. The arrangement'is such that when the article discharged presses down uponthe extended end, of the paddle 70 the lever 68 is rocked (clockwise Fig. 2) thus rocking toggle lever 31. in an opposite direction against the action of the toggle spring 35. When. toggle lever 31 has rocked over center the spring 35. urges it the balance of the way toward normal or reset position.

With the return of the toggle lever 31 to normal posi: tion the coin carriage 37 is positively moved forward to coin receiving position by its linkage 46 with the toggle lever. The plunger actuated lever 48.. is likewise shifted. with the coin carriage and by action of its return spring 51. vThe return of toggle lever 31 to normal position also withdraws the carriage gate 11 from discharge position so that the bottomless frame 15 registers with the lower end of passage P to receive the next article therefrom.

If per chance the last article stored in the machine ,was discharged on the last operation of the coin control 20 no article will be deposited on the shelf 14. Consequently, should anyone deposit a coin or coins in the slot 21 there is no way of obtaining a refund. However, a shutter, is arranged for sliding movement on the inner face of the front wall F of the cabinet. vThis shutter 80 is disposed for sliding movement across the .coin'slot 21 to close the same against admittance of a coin into the runway 22. This shutter 80 is connected by suitable linkage to a lever 81 having its inner extremity 82 disposed for movement up through the ledge 14 for detecting whether or not an article is present. Therefore, when no article is presented to the ledge 14 the inner extremity 82 of lever 81 is free to pass up beyond the ledge 14 whereupon the shutter Si! is automatically moved into closing position relative to the coin slot 21. y

In connection with the foregoing it will be noted that the shutter 80 is moved to slot closing position each time a lowermost article is shifted .off of ledge 14 by movement of the carriage gate 11. Consequently, no coins can be inserted into the coin slot 21 while the coin carriage 37 is in article discharging position. This is to say, while the V-shaped pocket 56 is out of coin receiving position with respect to the discharge end of the detector means 23.

While the foregoing structure is in specific detail it,

will be apparent that'it is susceptible to variation, alterat'ion, and/or modification without departing'frorn the spirit of niy'inv'ention; I therefore desire to avail myself of all variations, alterations and/or modifications fairly coming within the purview of the appended claims.
